那些遇到过的问题

尽管在zlib.lib中链接,仍未解析的外部

RSu*_*hke 31 c++ zlib

我一直在尝试编译一个在VC++ 2010中使用zlib压缩的应用程序.

我明白了

error LNK2019: unresolved external symbol _inflateInit2_ referenced in function ...
Run Code Online (Sandbox Code Playgroud)

错误消息,如果我没有链接lib,这不会是不寻常的.我链接静态版本zlib库.

我已经设法让这些完全相同的libs和header配置在不同的解决方案中完美运行,因此这种行为非常出乎意料.

任何想法将不胜感激.

如果您正在使用contrib中提供的VS2010解决方案,请注意它已被窃听.zlibstat项目定义了ZLIB_WINAPI,它根据zlib FAQ用于打开STDCALL约定.只需从项目设置中删除它并重新编译lib.

  • +1另请注意,您也可以通过在主项目中定义ZLIB_WINAPI来解决问题. (15认同)
  • 天哪,谢谢你!维护者确实需要解决这个问题. (5认同)
  • 这应该是公认的答案.这为我节省了很多时间. (4认同)
  • @Magallo你可以在#include zlib.h之前"#define ZLIB_WINAPI" (3认同)
  • 生命保护,会永远注意到这一点 (2认同)

就我而言，我修改了

  • 配置 -> 链接器 -> 输入 -> 附加依赖项

读书ucrt.lib;vcruntime.lib;msvcrt.lib;kernel32.lib

这使得 libz 能够在 Windows 10 下使用 VS2015 进行构建

确保构建类型为 /MD

如果构建 libpng（需要 zlib），情况也是如此，相同的修改可以使用旧的默认“项目”文件成功构建。

您是否验证了您的 zlib 函数原型位于一个extern "C"块中？如果不是，则链接器将查找具有 C++ 损坏名称的函数，而 zlib.lib 将包含未损坏的 C 名称。

  • 根据标准 zlib.h 标头，所有函数原型都位于 extern“C”块中。 (2认同)
